the quake hit at rush hour; thousands of motorists were killed when freeways collapsed.

the buildings were constructed on unconsolidated, water-saturated, lakebeds and foundation failures were common.

numerous, poorly constructed, top heavy, concrete slab buildings collapsed.

the area was densely populated and right at the epicenter of a magnitude 8.5 quake.

The correct answer is C. Numerous, poorly constructed, top heavy, concrete slab buildings collapsed.

Explanation:

The 1988 Armenian earthquake occurred in the northern part of Armenia that belongs to a seismic belt. This earthquake had a magnitude of 6.8 and lasted only about 20 seconds, despite this the Earthquake was devastating to the zone as many buildings collapsed as this lead to more than 25,000 deaths. This occurred because during this period most of the buildings were poorly constructed as the structures were not stable or follow basic construction principles and they included heavy materials such as concrete or slab, due to this, once the earthquake hit them they collapsed. Thus, the reason the 1988 American earthquake result in around 25,000 deaths was "numerous, poorly constructed, top-heavy, concrete slab buildings collapsed".

the reform movements that arose during the antebellum period in america focused on specific issues: temperance, abolishing imprisonment for debt, pacifism, antislavery, abolishing capital punishment, amelioration of prison conditions (with prison's purpose reconceived as rehabilitation rather than punishment), the humane treatment of animals, the humane and just treatment of native americans, the establishment of public institutions for the care of the destitute, orphans, blind, and mentally ill, the establishment of public schools, the abolition of tobacco use, vegetarianism, health reform, homeopathic medicine, woman's rights (including, at first, especially the establishment of a woman's right to own property apart from her husband and her right to sue for divorce), and the amelioration of labor conditions (including higher pay, the right to form unions, the right to strike, and the demand for limits on the number of work hours, and safe working conditions).
